Is black loose stools during pregnancy first trimester normal?

If on IRON: The iron in the prenatal vitamin, or if you are even on a supplemental Iron pill can cause the stool to be black. Call your GYN to assure you are on an iron supplement. If so, most likely fine, but at next visit, you could always have your stool checked for heme to be safe. Best wishes. ...Read more

Color of stool: The color of your stool is a reflection of your diet. What you eat is digested and the waste products are left over as stool. If you feel something is abnormal then a gastroenterologist can investigate. ...Read more

Taking peptobismol : Peptobismol can indeed cause dark stools whether you are pregnant or not. Upper gastrointestinal bleeding can also do so. The concern is that you could be taking the peptobismol for a condition that causes bleeding. Check with your OB about the problem and have it evaluated. Be safe. Hope this helps. ...Read more

Possibly: Black stools, usually sticky and foul smelling, may be a sign of gastrointestinal bleeding. Iron supplements and pepto bismol will turn the stool color black even 2 days after taking it. If it continues you should have your stool checked for blood. ...Read more

Black Stool Normal?: I would predict that your prenatal vitamins have iron in them. Iron can lead to black stools. This is most likely normal. ...Read more

Probably not: Iron supplements will turn your stool black and correcting the anemia is safer for your baby than not. The assumption here is that the black stools are from the iron pills and not from bleeding from an unknown as yet site. Confirm with your OB gyn. ...Read more

Black Stool: Black, tarry, malodorous stool could be related to GI bleeding. However, if you are taking medication containing iron (such as prenatal vitamins) or peptobismal - those could cause black stools too. Please let your OB know so that this can be assessed. Take care. ...Read more

Iron or blood : If you are taking prenatal vitamins, which have extra iron in them, you might have this occur. Alternatively, you might have bleeding somewhere in your gastrointestinal tract (ex:bleeding ulcer) that should be further evaluated and worked-up. ...Read more
